The light-transmitting encapsulation layer can be formed on the substrate by means of injection molding, dispensing, molding and the like, so that the light-transmitting encapsulation layer is tightly combined with the black layer and the pixel unit. In some examples, the light-transmitting encapsulation layer may cover only all the pixel units on the front surface of the display backplane, and may also cover all the front surface of the display backplane while covering the pixel units on the front surface of the display backplane.
In some embodiments, the display module further comprises a moisture barrier 9, the moisture barrier 9 comprising at least one of: a first moisture barrier 901 disposed between the black layer 4 and the front surface of the display backplane 1; and a second moisture-proof layer 902 covering each light-emitting chip 3. For example, as shown in fig. 2, a schematic cross-sectional structure of a moisture-proof layer of a display module is shown, it should be noted that fig. 2 is a schematic cross-sectional structure of a moisture-proof layer 901 disposed between a black layer 4 and a front surface of a display backplane 1, as shown in fig. 3, another schematic cross-sectional structure of a moisture-proof layer of a display module is shown, as shown in fig. 3, a second moisture-proof layer 902 of fig. 3 covers each light-emitting chip 3, the moisture-proof layer 9 may include, but is not limited to, being formed by molding and hot pressing, and of course, the arrangement of the moisture-proof layer 9 may also include being disposed between the black layer and the front surface of the display backplane and covering each light-emitting chip, as shown in fig. 4, for example, a schematic cross-sectional structure of a moisture-proof layer of another display module is shown, as shown in fig. 4, the moisture-proof layer 9 is disposed between the black layer and the front surface of the display backplane 1 and covering each light-emitting chip 3, the side surface of the light-emitting chip 3 is located between a top light-emitting surface 10 and a bottom surface 11 thereof, it should be noted that the light-emitting chip 3 has two light-emitting surfaces 10 and a bottom surface 11, which are oppositely disposed, and the bottom surface 11 is disposed on the front surface of the display back plate 1.

Preferably, in this embodiment, the top surface of the black layer in the first region is higher than the top light-emitting surface of the light-emitting chip, so as to prevent light crosstalk between the pixel units. It should be noted that the top surface of the black layer is higher than the top light-emitting surface of the light-emitting chip, that is, at least a portion of the top surface of the black layer is higher than the top light-emitting surface of the light-emitting chip, and the top surface of the black layer is not higher than the top light-emitting surface of the light-emitting chip, that is, any portion of the top surface of the black layer is not higher than the top light-emitting surface of the light-emitting chip, but may include at least a portion thereof being flush with the top light-emitting surface of the light-emitting chip.
